Application of large aperture porous ceramic products

The product has high mechanical strength, chemical and physical stability system, high service life, and large aperture, high air permeability, small air resistance.

Features of large aperture porous ceramic:

(1) High mechanical strength

Porous ceramics are generally obtained by firing oxide or non-oxide ceramic powders at high temperatures. Although its porosity is high, the grain-to-grain binding strength at the grain boundary is high during the firing process of the pore wall. Therefore, it has excellent mechanical properties.

 

(2) Good stability

 Porous ceramic materials have good physical properties and chemical stability and can be used in harsh environments. Such as: acid and alkali resistance, high temperature resistance, thermal shock resistance, radiation resistance.

 

(3) High service life

Due to its good physical and chemical stability, porous ceramics can also have a high service life in harsh use environments. In special environments, the performance of some uses is degraded, but after some processing, its function can be restored.

 

The product has high mechanical strength, chemical and physical stability system, high service life, and large aperture, high air permeability, small air resistance.
